foreach() and strings

[afortaleza]

I tried to use foreach() with a string but it gave me the error that I provided a non valid value to foreach(). I've tried to reset() a string and it says that the string is not an array.

At the same time I can access a string value as an array, for example:

$str = "string";
echo $str[3];

This will output "i". Is a string an array or just a pseudo-array ? Can I use foreach with strings or I have to loop the string with while ? (that was my solution).

thx

i had to typecast the string to an array to get this to work.

<?
$str = "string";

foreach((array)$str as $value)
{
echo $value;
}
?>
